Chapter 9 Replacing DRAM on the Route Switch Processor
Upgrading or Replacing DRAM SIMMs on the RSP2
Removing RSP2 SIMMs
This section describes the procedure for removing RSP2 SIMMs.
Caution
To prevent ESD damage, handle SIMMs by the card edges only.
Figure 9-2
Releasing the RSP2 SIMM Spring Clips
Step 1
Turn off the system power and remove the RSP2. (If you have a Cisco 7507 or Cisco 7507-MX, see the
procedure in
Figure 3-8
; if you have a Cisco 7513, Cisco 7513-MX, or a Cisco 7576, see the procedure
in
Figure 3-14
.)
Step 2
Place the RSP2 on an antistatic mat or pad, and ensure that you are wearing an antistatic device, such as
a wrist strap. Position the RSP2 so that the faceplate is away from you and the edge connector is toward
you—the opposite of the position shown in
Figure 9-1
.
Step 3
Locate the DRAM SIMMs on the RSP2. The SIMMs occupy U33 and U21 in bank 0, and U12 and U4
in bank 1.
Step 4
Release the spring clips from the SIMM you want to remove and release the SIMM from the socket. (See
Figure 9-2
.)
Step 5
When both ends of the SIMM are released from the socket, grasp the ends of the SIMM with your thumb
and forefinger and pull the SIMM completely out of the socket. Handle the edges of the SIMM only;
avoid touching the memory module or pins and the metal traces (the metal fingers along the connector
edge of the SIMM) along the socket edge.

Pull the tabs away with
your thumbs, bracing your
forefingers against the
posts. Raise the SIMM
to a vertical position.
